Nontronite is a green clay mineral that belongs to the smectite group, alongside minerals such as montmorillonite and saponite. Named after the town of Nontron in France, where it was first discovered, nontronite is typically found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash layers. Its green color, ranging from pale to dark shades depending on iron content, makes nontronite a fascinating mineral for collectors, geologists, and mineral enthusiasts.
